A model on factors affecting nurses adoption of health information technology

Healthcare organisations are using Health Information Technology (HIT) to improve efficiency, reduce cost and reduce medical errors. This study focused on the factors that influence the acceptance of HIT among nurses in Saudi hospitals. This research used a 6 stage mixed-methods research approach. Literature was used to search for established models and frameworks of technology acceptance, and the many factors that could play a role. In the field study, the nature of practical HIT issues at the Prince Sultan Military Medical City (PSMMC) and the Heraa Hospital were studied, and combined with literature to create a HIT Implementation Issues Framework. The framework consolidates elements from the Technological, Organisational, Environmental and Human dimensions. The researcher participated in further PSMMC projects in the design and implementation of the new Cardio Pulmonary Resuscitation System and the Nurses and Pharmacists’ Communication System. From the implementation experience, pertinent factors were added to the Technology Acceptance Model and the “Nurses Acceptance Model” was proposed. The proposed model has eleven independent parameters, two dependent parameters, as well as seven moderators of key relationships. A questionnaire with 71 entries was distributed to over 2800 nurses in 52 wards in PSMMC. SPSS was used for data screening and descriptive statistics. The SmartPLS software was used for analysis and testing of the proposed hypotheses. The findings refined the “Nurses Acceptance Model” and highlight the significance of User Involvement and Training. The “Nurses Acceptance Model” enhances the scientific understanding of variables that affect technology acceptance among nurses in Saudi hospitals. The HIT Implementation Issues Framework helps hospital decision makers to plan HIT projects to improve the likelihood of successful adoption

Zirconia-calcium silicate bioactive composites for dental applications using DLP additive manufacturing

Zirconia has outstanding mechanical strength which made it a favourable material dental implants material. However, its use is limited by challenges in bone bonding and elasticity. This paper introduces a novel bioprinting ceramic material by mixing calcium silicate with zirconia to enhance bioactivity. Using the high precision and speed of Digital Light Processing (DLP), this study develops a novel zirconia-calcium silicate slurry for dental applications. The study reports the preparation of zirconia-calcium silicate, formulation of resin compositions, and optimization of the bioprinting, debinding and sintering. Employing a full factorial Design of Experiments (DOE), a systematic approach was implemented to identify optimal printing conditions such as the layer thickness, exposure time, and power. The results show that slurries formulated with BYK-111 as the dispersant and ACMO/PEGDA/TPO resin, coupled with 80 wt.% solid loading, achieved the most favourable rheological properties, cure depth, and printing accuracy. The optimal printing conditions were 0.75 s exposure time, 300% exposure power, and 30 µm layer thickness, ensured a relative density of the sintered implants exceeding 95%. This study advances dental implant materials by introducing a novel DLP biomaterial with a slurry formulation, presenting significant implications for clinical applications and future research in developing advanced dental and medical implants

N-functionalised expanded-ring N-heterocyclic carbenes: Synthesis, structure and catalysis

The work presented in this thesis is concerned with the synthesis, metal coordination and applications of expanded (6- and 7-membered) N-functionalised heterocyclic carbenes. It is divided into four chapters, which cover the following areas of research. Chapter One includes the historical and literature review of preparations, reactions, and catalysis applications for different-types of NHC, while in Chapter Two, the syntheses characterisation and solid state properties of new 6- and 7-membered NHC salts (with Mes, DIPP, o-MeOPh and o-MeSPh A/-substituents) are discussed. A new method for synthesising saturated NHC salts, using potassium carbonate as a mild base for the deprotonation of the corresponding formamidines reacted with di-electrophiles under aerobic conditions is presented. Chapter Three describes the syntheses characterisation and solid state structure of rhodium and iridium complexes. Expansion of the ring provides carbenes with NCnhcN angle close to the sp2 angle (120 ), which forces the A/-substituents to bend closer to the metal center. Furthermore, the expanded carbenes are found to be more basic than their 5-membered analogues. The wide NCnhcN angles and greater donor abilities of the expanded NHC carbenes mean that their catalytic applications are interesting to study. Chapter Four presents the results of catalytic performance for the 6- and 7-membered NHC rhodium and iridium complexes in olefin hydrogenation reactions with molecular hydrogen. These complexes are also tested as catalysts in the transfer hydrogenation of ketones

Use of ring-expanded diamino- and diamidocarbene ligands in copper catalyzed azide-alkyne "click" reactions

The two-coordinate ring-expanded N-heterocyclic carbene copper­(I) complexes [Cu­(RE-NHC)₂]⁺ (RE-NHC = 6-Mes, 7-<i>o</i>-Tol, 7-Mes) have been prepared and shown to be effective catalysts under neat conditions for the 1,3-dipolar cycloaddition of alkynes and azides. In contrast, the cationic diamidocarbene analogue [Cu­(6-MesDAC)₂]⁺ and the neutral species [(6-MesDAC)­CuCl]₂ and [(6-MesDAC)₂(CuCl)₃] show good activity when the catalysis is performed on water

An Evaluation of the Second Intermediate Saudi English Language Textbook from the Teachers' Point of View

The study evaluates the quality of the second intermediate grade English language textbook for Saudi girls' schools "from the teachers point of view" which was introduced at the intermediate stage by the Ministry of Education in 2004. This research project evaluates a new textbook that is considered to be the foundation stone in the English language program in Saudi Arabia. A survey questionnaire was used in this study to elicit the perspectives of 50 English language teachers and the population is about 220 teachers in Riyadh Educational Zone about the textbook in question. The questionnaire consisted of 23 items grouped under 5 main categories that are listed as: CB objectives, content, language style, skills, technical aspect and appearance of the CB. The data was subjected to analysis through descriptive statistics. The analysis of the results used several statistical methods which are as follows: Cronbach's alpha, means, percentage, chi square and standard deviations. The findings were generally in favor of the textbook except for the language style and some other sub-items. Out of 23 items in the questionnaire, only 4 items had arithmetic means less than 3.50 (the average). The category that had the highest mean was the one on technical aspects, while the category that had the lowest mean was the one on language style.Keywords:  Evaluation, textbook, content, curriculum and syllabus, goals and objectives, materials evaluatio

Riyadh Blood Banks Distribution System

In each hospital, the priority to ensure a patient\u27s live is high. Therefore, a health department strives to build best medical facilities and hire superior staff to meet patient\u27s needs. The Saudi Ministry of Health has the highest budget\u27s portion among other ministries, yet, there are many projects that need to be implemented as soon as possible in order to save the most lives. Blood availability is considered to be one of the top needs at each hospital; however, blood banks in Saudi Arabia collect only 40% of the blood while 60% is collected by patients\u27 families. To increase the blood availability, this paper presents a holistic project to support the trend toward 100% voluntary blood donations. By applying System Engineering discipline, the project aims to ensure communication and distribution between blood banks in the city of Riyadh and also connects thirty-four hospitals of different sectors, them being public, private, and military. Since blood availability is a national duty, the Ministry of Health will be responsible for launching and operating the project. So, blood banks will work together under the umbrella of the General Department of Laboratories and Blood Banks to achieve the system\u27s objective
