    Get PDF
    Cranioplasty is the surgical repair of a deficiency or deformity of the skull. The purpose of cranioplasty is to provide protection for the brain following cranial surgery, and to offer relief to psychological disadvantages while increasing social performance. There are several materials that had been used for cranioplasty, but an ideal product has yet to be developed, hence the ongoing research into biologic and non-biologic alternatives to the existing materials. This article critiques the products currently used for cranioplasty in order to facilitate the development of new materials, which can improve patient outcomes

    Common Treatments and Procedures Used for Fractures of the Distal Radius and Scaphoid: A Review

    Get PDF
    The distal radius and the scaphoid are the most commonly injured carpal bones among both active adults and the osteoporotic elderly. The purpose of surgical treatment is to restore form and function to the wrist. Depending on the nature of the fracture, either topical procedures or invasive surgery can be applied. This article critiques the treatments currently used for fixation of wrist fractures in order to drive the development of new materials to improve patient outcomes

    An Empirical Study on the Influence of Online Service Quality on Customer Satisfaction: A Study of Royal Jordanian Airline

    Get PDF
    The aims of this paper is to examine the relationships of online service quality dimensions with customers’ satisfaction towards e-ticket system in Royal Jordanian Airlines. The proposed instrument dimensions are identified based on a questionnaire survey conducted in Jordan. Based on an extensive review of literature, this paper proposed five dimensions for measuring online service quality on customer satisfaction. The results show significant relationships among the online service quality dimensions (Responsiveness, Contact, Efficiency and privacy), and customer satisfaction. The results are important to enable managers to have a better understanding of the key online service quality dimensions that influence customer satisfaction. The primary limitations of this research are the scope and size of its sample. Keywords: online service quality, Responsiveness, Compensation, Contact, Efficiency and privacy and customer satisfaction

    A Predictive Technique using Random Forest Classifier for Phishing Malicious Attack

    A person with an email account is always vulnerable to fraud. An email account can be exploited by using a type of social engineering attack where the attackers trick the victims to steal user credentials by masquerading as a trusted entity. Email phishing has become the major action performed in various sectors such as banking, business, any enterprise or social media etc. While the action of phishing, the attackers make use of another technique called email spoofing. Email spoofing is not much different from email phishing since the email spoofing involves the usage of forged email header pretending as an entity created by a person of a trusted source. Phishing always has a malicious intent which means the person behaves knowingly or purposefully to cause them harm without a legal reasoning. Since the globe has more victims, we come across a large dataset. The major objective of the study is to determine the performance factors based on the phishing using random forest classifiers. For analysing a predictive model, we need a proper technique or an algorithm. In this case the random forest algorithm is accurate because it is built with many decision trees that produce a predictive model about the error rate

    Maxillary Tuberosity Reconstruction with Transport Distraction Osteogenesis

    Severe bone loss due to pathology in the maxillary tuberosity region is a challenging problem both surgically and prosthetically. Large bone grafts have a poor survival rate due to the delicate bony architecture in this area and presence of the maxillary sinus. Our case presentation describes a new technique for reconstructing severe bony defect in the maxillary tuberosity with horizontal distraction osteogenesis in a 45-year-old man. A 4 × 6 × 3 cm cyst was discovered in the left maxillary molar region and enucleated. Three months postoperatively, the area had a severe bone defect extending to the zygomatic buttress superiorly and hamular notch posteriorly. Three months later, a bone segment including the right upper second premolar was osteotomised and distracted horizontally. The bone segment was distracted 15 mm distally. After consolidation, implants were placed when the distractor was removed. A fixed denture was loaded over the implants after 3 months. Complete alveolar bone loss extending to the cranial base can be reconstructed with transport distraction osteogenesis. Distalisation of the alveolar bone segment adjacent to the bony defect is an easy method for reconstructing such severe defects

    Supply Chain Management and Organizational Performance: The Moderating Effect of Supply Chain Complexity

    Get PDF
    This study investigates the relationship between various factors in supply chain management (customer relationship, level of information, sharing postponement, sharing quality of information, and strategic supplier partnership) and their impact on organizational performance. This research relies on primary data collected through the use of questionnaires. The research will concentrate on Jordans tourist industry. Only 261 were approved and examined using SmartPLS.The results of the study indicate that sharing postponement, sharing quality of information, and strategic supplier partnership have a strong positive impact on organizational performance. However, the relationship between customer relationship and organizational performance is not statistically significant. The relationship between level of information and organizational performance is statistically significant. These findings suggest that organizations can improve their performance by implementing strategies to manage and optimize these factors in their supply chain. This study also evidenced that Supply Chain Complexity as moderator helps increase organiizational performance by interacting with Strategic Supplier Partnership, Level of Information, Sharing Quality of Information, Sharing Postponement. However, it should be noted that there is some inconsistency in the results compared to previous studies, and the relationship between these factors and organizational performance is still not fully understood. This highlights the need for further research in this area to gain a better understanding of how these factors impact organizational performance

    Visitor Management System Design and Implementation during the Covid-19 Pandemic

    In todays computer technology environment, the effect of IT plays a significant part in all real-time systems. Various management systems are in place to help the company organization achieve profit, standards, and future commercial growth. The VMS is important for monitoring how many visitors are there, what the objective of the facility visit will be, and who will be put in the block listed record due to rule violation. This technology also protects the buildings overall security. The goal of this system is to synchronize the organizations business and visitors in order to achieve a wonderful connection among organizations globally. The background was compiled from many papers that discussed similar subjects and were connected to the system. In addition, the limitations and analyses of the present system have been addressed in order to demonstrate the organizations demands for a new system. In part three, we will go through the project planning, covering the feasibility study, Gantt chart, and software methodology in specific stages. Stepping on functional and non- functional requirements of the system, it is covered in the same chapter, as well as the system steps in the implementation part of section four, and finally with clear and direct conclusion and recommendations in section five with future work of the visitor management system, which will be added after the system is implanted in the organization and other related organizations
