Examining The Potential For Vitamin D Deficiency In Young Saudi Women Living In Canada: A Qualitative Study

More than a billion people worldwide suffer from vitamin D deficiency or insufficiency. Canada, which has a long winter and high latitude, has a high rate of vitamin D deficiency. The Middle East also, in particular Saudi Arabia, has one of the highest rates of vitamin D deficiency in the world. The purpose of this research was determining the knowledge, attitudes, and practices (KAP) concerning vitamin D of young Saudi women living in Canada. Health professionals with experience in both Canada and Saudi Arabia acted as key informants. This research assessed topics related to knowledge of vitamin D sources (supplementation, fortification, and exposure to the sun), attitudes regarding the importance of vitamin D, and practices indicating whether knowledge and attitudes were being implemented or not. The study was conducted in Canada. Eight Saudi women between the ages of 18- 45 y and 10 health professionals including physicians, nutritionists and nurses were recruited. Results showed that Saudi women had limited awareness of vitamin D deficiency and lacked motivation to use supplements. They also had limited sun exposure due to environmental and cultural reasons. The health professionals recommended that Saudi women increase their awareness of the risk of vitamin D deficiency and the importance of using vitamin D supplements. Recommendations for more research about Saudi women living in northern locations such as Canada are presented

A proposed Vision for the Leadership of Education Institutions on Gifted Caring in Light of Participative Leadership

The study aims to identify the status of gifted caring in education institutions in the Kingdom of Saudi Arabia (KSA). It also attempts to identify the degree of practice by the two heads of participative leadership from the perspective of supervisors in the management of gifted caring. Thus, the study eventually aims to provide a proposed vision for education institutions of gifted caring in light of participative leadership. The study adopted the descriptive survey approach together with the descriptive-analytical method. The study sample involved (102) supervisors. The population comprised all male and female supervisors working for the ministry of education in KSA whose number amounted to (206) supervisors in addition to all ministry circulars related to gifted caring and all relevant studies that tackled education institution leadership in light of the precipitative type. The researchers designed a questionnaire of four dimensions which included (31) items. The study's foremost results revealed that the administration leadership status ranked “medium.” As for the practice of the two heads of the gifted, caring leadership, it also ranked “medium” for all domains, which are: management duties, authorization, human relations, and finally, media and communication domains. The researchers also proposed a vision for the leadership of educational institutions for gifted caring in light of participative leadership by designing an integrated model for the issue. The researchers also put down specific steps to be followed in applying the vision. The study concludes with numerous recommendations and suggestion

Unsupervised grounding of textual descriptions of object features and actions in video

We propose a novel method for learning visual concepts and their correspondence to the words of a natural language. The concepts and correspondences are jointly inferred from video clips depicting simple actions involving multiple objects, together with corresponding natural language commands that would elicit these actions. Individual objects are first detected, together with quantitative measurements of their colour, shape, location and motion. Visual concepts emerge from the co-occurrence of regions within a measurement space and words of the language. The method is evaluated on a set of videos generated automatically using computer graphics from a database of initial and goal configurations of objects. Each video is annotated with multiple commands in natural language obtained from human annotators using crowd sourcing

Families, nurses and organisations contributing factors to medication administration error in paediatrics: a literature review

Background: Medication error is the most common adverse event for hospitalised children and can lead to significant harm. Despite decades of research and implementation of a number of initiatives, the error rates continue to rise, particularly those associated with administration. Objectives: The objective of this literature review is to explore the factors involving nurses, families and healthcare systems that impact on medication administration errors in paediatric patients. Design: A review was undertaken of studies that reported on factors that contribute to a rise or fall in medication administration errors, from family, nurse and organisational perspectives. The following databases were searched: Medline, Embase, CINAHL and the Cochrane library. The title, abstract and full article were reviewed for relevance. Articles were excluded if they were not research studies, they related to medications and not medication administration errors or they referred to medical errors rather than medication errors. Results: A total of 15 studies met the inclusion criteria. The factors contributing to medication administration errors are communication failure between the parents and healthcare professionals, nurse workload, failure to adhere to policy and guidelines, interruptions, inexperience and insufficient nurse education from organisations. Strategies that were reported to reduce errors were double-checking by two nurses, implementing educational sessions, use of computerised prescribing and barcoding administration systems. Yet despite such interventions, errors persist. The review highlighted families that have a central role in caring for the child and therefore are key to the administration process, but have largely been ignored in research studies relating to medication administration. Conclusions: While there is a consensus about the factors that contribute to errors, sustainable and effective solutions remain elusive. To date, families have not been included as key stakeholders in researching or developing effective interventions to reduce medication administration errors

Securing Low-Power Blockchain-Enabled IoT Devices Against Energy Depletion Attack

Blockchain-enabled Internet of Things (IoT) envisions a world with rapid development and implementations to change our everyday lives based on smart devices. These devices are attached to the internet that can communicate with each other without human interference. A well-known wireless network in blockchain-enabled IoT frameworks is the Low Power and Lossy Network (LLN) that uses a novel protocol known as Routing protocol for low power and lossy networks (RPL) to provide effective and energy-efficient routing. LLNs that run on RPL are inherently prone to multiple Denial of Service (DoS) attacks due to the low cost, shared medium. and resource-constrained nature of blockchain-enabled IoT devices. A Spam DODAG Information Solicitation (DIS) attack is one of the novel attacks that drain the energy source of legitimate nodes and ends up causing the legitimate nodes to suffer from DoS. To address this problem, a mitigation scheme named DIS Spam Attack Mitigation (DISAM) is proposed. The proposed scheme effectively mitigates the effects of the Spam DIS attack on the network’s performance. The experimental results show that DISAM detects and mitigates the attack quickly and efficiently

Numerical algorithm for solving second order nonlinear fuzzy initial value problems

The purpose of this analysis would be to provide a computational technique for the numerical solution of second-order nonlinear fuzzy initial value (FIVPs). The idea is based on the reformulation of the fifth order Runge Kutta with six stages (RK56) from crisp domain to the fuzzy domain by using the definitions and properties of fuzzy set theory to be suitable to solve second order nonlinear FIVP numerically. It is shown that the second order nonlinear FIVP can be solved by RK56 by reducing the original nonlinear equation intoa system of couple first order nonlinear FIVP. The findings indicate that the technique is very efficient and simple to implement and satisfy the Fuzzy solution properties. The method’s potential is demonstrated by solving nonlinear second-order FIVP

Utilization of Multimedia Services in Libraries for Students with Disabilities

This study has two primary objectives: first, to determine whether or not students with visual impairments make use of multimedia services, and second, to compile a list of the challenges that handicapped face while attempting to use such services. This research was a descriptive qualitative field study that used a qualitative technique of qualitative description. In addition to interviews and written documentation, observation was another method that was used while compiling this data. The study is significant as it shows the availability of media services in schools’ libraries for students with disabilities. According to the findings of this investigation, pupils seem to make effective use of the multimedia services provided by the library for patrons with disabilities. The library offers a variety of services and amenities. Students use of technology, such as laptops and projectors, to get access to material via both visual and audible channels might be seen as evidence that they have achieved this goal. The inadequacy of the service infrastructure and the antiquated nature of the technology makes it difficult to make use of the benefits offered by multimedia services. In addition, there is a severe lack of librarians with experience working with multimedia technology in the worlds educational institutions at the present moment

Towards Wind Energy-based Charging Stations: A Review of Optimization Methods

Due to the growing importance of renewable sources in sustainable energy systems, the strategic deployment of robust optimization techniques plays a crucial role in the design of Electric Vehicle Charging Stations (EVCSs). These stations need to smoothly incorporate renewable sources, ensuring optimal energy utilization. This study provides a comprehensive overview of the methodologies and approaches employed in the enhancement of wind energy based EVCSs. The aim is to discern the most efficacious techniques for optimizing charging stations. Researchers engage diverse strategies and methodologies in the realm of sizing and optimization, encompassing a spectrum of algorithmic implementations and software solutions. Evidently, each algorithm or software application bears distinctive merits and demerits. Singular reliance on a solitary algorithm or software for charging utility optimization is discerned to be potentially limiting. The investigation reveals that achieving better results in Electric Vehicle Charging Station (EVCS) optimization is facilitated by the collaborative use of multiple algorithms like GA, PSO, and ACO, among others, or software tools like Homer or RETScreen
