Internet of Things (IoT) devices incorporate a large amount ofdata in several fields, including those of medicine, business, and *** authentication is paramount in the IoT era to assure connecteddevices’ security. However, traditional authentication methods and conventionalbiometrics-based authentication approaches such as face recognition,fingerprints, and password are vulnerable to various attacks, including smudgeattacks, heat attacks, and shoulder surfing attacks. Behavioral biometrics isintroduced by the powerful sensing capabilities of IoT devices such as smartwearables and smartphones, enabling continuous authentication. ArtificialIntelligence (AI)-based approaches introduce a bright future in refining largeamounts of homogeneous biometric data to provide innovative user authenticationsolutions. This paper presents a new continuous passive authenticationapproach capable of learning the signatures of IoT users utilizing smartphonesensors such as a gyroscope, magnetometer, and accelerometer to recognizeusers by their physical activities. This approach integrates the convolutionalneural network (CNN) and recurrent neural network (RNN) models to learnsignatures of human activities from different users. A series of experiments areconducted using the MotionSense dataset to validate the effectiveness of theproposed method. Our technique offers a competitive verification accuracyequal to 98.4%.We compared the proposed method with several conventionalmachine learning and CNN models and found that our proposed modelachieves higher identification accuracy than the recently developed verificationsystems. The high accuracy achieved by the proposed method proves itseffectiveness in recognizing IoT users passively through their physical activitypatterns.

Self-Care Management Practices of Diabetic Patients Type 2 in Saudi Arabia

引用

Open Journal of Nursing 2020年第11期10卷 1013-1025页

作者： Budour bandar alotaibi Prince Sultan Military Medical City Riyadh KSA

Background & Aim: Patients’ self-care management practice in diabetes is considered a critical element to keep diabetes under control and the disease management is usually conducted by the patients themselves and/or their families. The main aim of this study is to assess the level of self-care management practices of diabetic patients type 2 in Saudi Arabia. Materials & Methods: A cross-sectional study design was utilized in the Prince Sultan Military Medical City in Riyadh on a convenience sampling method consisted of 377 diabetic patients type 2. The researcher used a self-administered questionnaire (Summery of Diabetes Self-care Activities) which was adopted from Toobert et al. (2000). Results: The study results revealed that the level of self-care management practices among patients with type 2 DM is not satisfactory, except in the medication domain. Conclusion & Recommendations: Policymakers should revise the education strategy for diabetic patients and develop health education campaigns that focus on the patient’s family as well as the individual with type-2 DM.

A novel extended Lindley lifetime model that exhibits unimodal or decreasing density shapes as well as increasing,bathtub or unimodal-then-bathtub failure rates, named the Marshall-Olkin-Lindley (MOL) model is *** this research, using a progressive Type-II censored, various inferences of the MOL model parameters oflife are introduced. Utilizing the maximum likelihood method as a classical approach, the estimators of themodel parameters and various reliability measures are investigated. Against both symmetric and asymmetric lossfunctions, the Bayesian estimates are obtained using the Markov Chain Monte Carlo (MCMC) technique with theassumption of independent gamma priors. From the Fisher information data and the simulatedMarkovian chains,the approximate asymptotic interval and the highest posterior density interval, respectively, of each unknownparameter are calculated. Via an extensive simulated study, the usefulness of the various suggested strategies isassessedwith respect to some evaluationmetrics such as mean squared errors, mean relative absolute biases, averageconfidence lengths, and coverage percentages. Comparing the Bayesian estimations based on the asymmetric lossfunction to the traditional technique or the symmetric loss function-based Bayesian estimations, the analysisdemonstrates that asymmetric loss function-based Bayesian estimations are preferred. Finally, two data sets,representing vinyl chloride and repairable mechanical equipment items, have been investigated to support theapproaches proposed and show the superiority of the proposed model compared to the other fourteen lifetimemodels.

Open Journal of Nursing 2020年第7期10卷 657-664页

作者： Budour bandar alotaibi Alanoud Essam Almadani Olfat Salem Prince Sultan Military Medical City Riyadh KSA Al-Iman General Hospital Riyadh KSA King Saud University Riyadh KSA

Background: The absence of patient safety culture among nurses has been linked to increased errors and higher level of mortality and morbidity among patients. Higher culture of patient safety has been shown to be associated with better patient outcomes, and the implementation of improvements in organizational and safety culture enhances quality in healthcare. Aim: The main aim of this study is to assess the perception of nurses regarding patient safety among nurses at prince sultan military medical city in Saudi Arabia. Materials and Methods: Cross-sectional design was applied in this study among nurses who are working at prince sultan military medical city in Riyadh, Saudi Arabia. Sample was 215 nurses, selected by convenience sampling method. The Hospital Survey on Patient Safety Culture (HSOPS) survey was used in the current study to collect data. Data have been collected within seven weeks. Statistical package for social sciences has been used to analyze data using descriptive statistics and inferential statistics such as Independent sample t test and One-Way ANOVA. Results and Conclusion: The results can only be useful if data analysis is described. The highest domain of their perception was illustrated in “Hospital management support for patient safety” with a mean of 3.68 out of 5.0, while, the lowest mean for their perception was in the domain of “Teamwork across hospital units” with a mean 2.62. The total mean of nurses’ perception regarding patient safety was 3.19 out of 5.0. Also, there was a significant difference in the mean level of nurses’ perception of patient safety with regard to nurses’ gender. Encouraging patients’ safety culture among nurses is strongly recommended through effective communication and providing feedback.

Alloantibodies that are non ABO Alloimmunization to protein antigens happens only after exposure, in contrast to ABO isohaemagglutinins, which are present naturally, even in the absence of prior exposure. It is recognized that while non-ABO RBC antibodies are less common than ABO antibodies, they generate essentially the same issues that lead to unfavorable clinical results. If non-ABO alloantibodies are identified early on, these issues related complications may be avoided This call for an in-depth understanding of the recipient and donor’s ABO-Rh grouping, antibody screening, and the phenotype of certain antigens. Equally important, the temporal association time between transplantation and hemolysis can help identify the underlying mechanism of hemolysis and direct appropriate management. Therefore, for that, it is crucial to identify the etiology of post-HSCT anemia for prevention and therapy, in addition to a thorough grasp of the mechanism of anemia in non-ABO-incompatible HSCT and the temporal link between HSCT and anemia. Finding the cause of post-HSCT anemia is essential for prevention and therapy, in addition to a thorough grasp of the mechanism of anemia in non-ABO-incompatible HSCT and the temporal link between HSCT and anemia. Therefore, for that, it is crucial to identify the etiology of post-HSCT anemia. In this case report review, we would like to highlight the vital role of transfusion medicine services and stem cell clinical teams in paying particular attention to the clinical significance of non-ABO alloantibodies involved to avoid causing overt hemolysis of incompatible donor RBCs or delayed erythropoiesis. Considering the fact that some of the Haematopoietic stem cell transplant centers do not give an attention to the other non-ABO RBC antigens.
