Physical Child Abuse by Parents and Teachers in Saudi Arabia:A Systematic Literature Review

A systematic review was conducted to find out what is known about the prevalence and nature of physical child abuse in Saudi. The review identified 15 abuse prevalence studies carried out in Saudi Arabia between 1998 and 2016, written in English or Arabic. An analysis of these revealed the known relative prevalence of different types of child abuse, the relationship of the abuser to the victim, and the level of awareness among school professionals of procedures and programs in Saudi to protect children from abuse. The review revealed many shortcomings of the existing literature, including a paucity of published studies, lack of rigor in research design, an absence of data from many parts of the country, and an emphasis on hospital reports rather than data collected directly from victims. Studies conducted to date suggest that physical abuse of children is more widespread and severe in the Kingdom than previously acknowledged

Fitting the refractive indices of GaN at different conditions with MATLAB codes for optical simulations

This mixed study presents the optical properties of gallium nitride material at different conditions and thicknesses over a very wide wavelength range for optical simulations. The availability of optical properties of gallium nitride over a very wide wavelength range facilitates the use of gallium nitride in different simulated optical devices such as laser diodes, LEDs, and other optical and electronic devices. Fitted equations, plotted figures, and MATLAB codes for refractive indices will be presented to reduce mistakes within simulations.Deanship of Graduate Studies and Scientific Research at University of BishaThe authors are thankful to the Deanship of Graduate Studies and Scientific Research at University of Bisha for supporting this work through the Fast-Track Research Support Program

Periodic open and closed resonators as a biosensor using two computational methods

The volatile particles and molecules in our dry exhaled breath can reveal enormous information about the health of any person, such as the person’s respiratory and metabolic functioning. Beyond the carbon dioxide level is an indicator of life, it provides important health-related data like people’s metabolic rate. This study considers periodic open and closed resonators for measuring carbon dioxide concentration in dry exhaled breath. Transfer matrix and green methods are used to simulate the interaction between acoustic waves and the proposed sensor. The band gaps using the green method coincide with the transmittance spectra by the transfer matrix. The suggested sensor recorded a sensitivity of 5.3Hz.m-1.s, a figure of merit of 10,254 m-1.s, a detection limit of 5×10-6m.s-1, and a quality factor of 3×106. Furthermore, the efficiency shows that the proposed design is appropriate as a diagnostic sensor for different diseases such as chronic obstructive pulmonary. Besides, cylindrical-adapted sensors are urgently needed in medicine, industry, and biology because they can simultaneously be used for fluid transport and detection. © The Author(s) 2024.King Khalid University, KKU; Deanship of Scientific Research, King Khalid University, (2/46/45); Deanship of Scientific Research, King Khalid UniversityFunding text 1: The current work was assisted financially to the Dean of Science and Research at King Khalid University via the Large Group Project under grant number RGP. 2/46/45. ; Funding text 2: The authors extend their appreciation to the Deanship of Scientific Research at King Khalid University for funding this work through large Groups Project under grant number RGP. 2/46/45

Exploring the anticancer potential of Costus speciosus: a comprehensive review

Abstract Costus speciosus is a medicinal plant with a long history in Indian Ayurvedic medicine, recognized for its diverse bioactive properties, including antibacterial, anticancer, anti-inflammatory, and antidiabetic effects. This review highlights its therapeutic potential, particularly in cancer treatment, where its bioactive compounds exhibit cytotoxic effects against breast, ovarian, and uterine cancers. These compounds have shown the ability to induce apoptosis, regulate the cell cycle, and inhibit cancer progression, offering a promising alternative to conventional chemotherapy with potentially fewer side effects. Additionally, C. speciosus demonstrates antioxidant, antimicrobial, and antidiabetic properties, expanding its clinical applications. Despite its promising pharmacological profile, further research is required to understand the molecular mechanisms underlying its therapeutic effects and ensure the safety and efficacy of its various extracts for therapeutic use

Bilateral Spontaneous Hyphema in Juvenile Xanthogranuloma: A Case Report

Juvenile xanthogranuloma (JXG) is an idiopathic granulomatous inflammatory condition that usually affects children. Intraocular involvement, especially bilateral, is rare in JXG. Most patients with ocular lesions are typically infants and usually present with hyphema, iridocyclitis, and secondary glaucoma. We report a case of a 3-month-old baby girl who presented to our emergency department with bilateral hyphema that started 3 weeks ago. She was medically free with no history of any recent trauma or preceding febrile illness. General physical examination showed a quiet baby with multiple hyperpigmented macules over the inner thigh and right upper arm, with one pinkish nodule over the occiput. She also had high intraocular pressures. A detailed ophthalmic assessment was done under general anesthesia. The nodular lesion was excised and sent for histopathological evaluation, which confirmed the diagnosis of JXG. Treatment of JXG cases present a challenge to ophthalmologist due to rebleeding and refractory glaucoma. Our case was admitted multiple times for rebleeding and refractory glaucoma and was treated with full antiglaucoma drops, steroid drops and peribulbar injection of steroid. </jats:p

A Machine Learning Approach to Career Path Choice for Information Technology Graduates

Enterprises rely more and more on well-qualified and highly specialized IT professionals. Although the increasing availability of IT jobs is a good indicator for IT graduates, they nonetheless may find themselves confused about the most appropriate career for their future. In this paper, a recommendation system called CareerRec is proposed, which uses machine learning algorithms to help IT graduates select a career path based on their skills. CareerRec was trained and tested using a dataset of 2255 employees in the IT sector in Saudi Arabia. We conducted a performance comparison between five machine learning algorithms to assess their accuracy for predicting the best-suited career path among 3 classes. Our experiments demonstrate that the XGBoost algorithm outperforms other models and gives the highest accuracy (70.47%).</jats:p

CORRESPONDANCES ENTRE L'ARTICULATOIRE ET L'ACOUSTIQUE DANS LE TIMING VOYELLE-CONSONNE. Données arabes et françaises.

Cette étude vise à rendre compte des possibles corrélations articulatori-acoustiques dans le contrôle du timing vocalique et consonantique et ce pour un articulateur "porteur", la mandibule. Notre objectif consistera donc à examiner le comportement de deux tâches linguistiques différentes, - la longueur vocalique et la gémination consonantique -, à travers deux conditions de vitesse (normale et rapide), en française et pour deux dialectes d'une langue non apparentée, l'arabe (tunisien et koweïtien).This research work examines possible articulatori-to-acoustic correlations in the control of vocalic and consonantal timing gestures for a specific "carrier" articulator, the mandible. The objective is to probe into the behaviour of two different linguistic-timed tasks - vowel length and consonant gemination -, across two speaking rate conditions (conversational and fast), in French and two dialects of an unrelated language, Arabic (Tunisian and Kuweiti)
