Ipv4 Address

The IP-multicast transmission is the IP level answer for the growing one-to-many content spreading needs in multimedia applications (Hosszú, 2005). Nevertheless the address allocation and service discovery is a problematic field of this technology. Despite of the efficiency of the IP-multicast it has not been deployed in the whole Internet. Especially the global address allocation is a problematic part of the Internet-wide multicasting. This article addresses such problems in order to review the existing methods and the emerging research results. The IP-multicasting uses a shared IPv4 address range. In Internet-wide applications the dynamic allocation and reuse of the addresses is essential. Recent Internet-wide IP-multicasting protocols (MBGP/ MSDP/PIM-SM) have a scalability or complexity problem. The article introduces the existing solution for the wide-area multicasting and also proposes a novel method, which overcomes the limitations of the previous approaches.

The development of a scanning electron microscope (SEM) suitable for instructional purposes has created a large number of outreach opportunities for the Materials Science and Engineering (MSE) Department at Iowa State University. Several collaborative efforts are presently underway with local schools and the Department of Curriculum and Instruction (C&I) at ISU to bring SEM technology into the classroom in a near live-time, interactive manner. The SEM laboratory is shown in Figure 1.Interactions between the laboratory and the classroom use inexpensive digital cameras and shareware called CU-SeeMe, Figure 2. Developed by Cornell University and available over the internet, CUSeeMe provides inexpensive video conferencing capabilities. The software allows video and audio signals from Quikcam™ cameras to be sent and received between computers. A reflector site has been established in the MSE department that allows eight different computers to be interconnected simultaneously. This arrangement allows us to demonstrate SEM principles in the classroom. An Apple Macintosh has been configured to allow the SEM image to be seen using CU-SeeMe.

The development of a modern e-learning system promotes the active introduction of distance education. The organization of a mixed form of education at the department of Clinical Pharmacology and Pharmacotherapy involves an education during the session and using the distance contact between faculty and students during the intersessional period. The information technology system of distance learning is provided by personal computers, video and audio equipment. The web-site of the department presents a set of teaching materials, including curriculas, work programs, lecture notes, test assignments, situational tasks, control and individual course work. Distance learning is supplemented with new teaching materials: web lectures, e-learning textbooks and manuals. Lectures are delivered by faculty members in the form of video conferences or webinars. Consultations are conducted in the on-line mode each week at a certain time by the teachers of the department according to the schedule. The website of the department presents methods for implementing practical skills, video stories of individual urgent states on the pathology of internal organs, demonstrates sets of medicines for seven types of first aid kits to improve the students' knowledge and skills, and to successfully pass the practical part of the state certification of graduates from the discipline "Clinical pharmacy".

Paroxysmal Positional Vertigo

Abstract Introduction Telehealth consists in the application of technology to provide remote health service. This resource is considered safe and effective and has attracted an exponential interest in the context of the COVID pandemic. Expanded to dizzy patients, it would be able to provide diagnosis and treatment, minimizing the risk of disease transmission. Benign paroxysmal positional vertigo (BPPV) is the most common vestibular disorder. The diagnosis typically rests on the description of the symptoms along with the nystagmus observed at a well-established positional testing. Objectives The aim of the present study was to propose a teleconsultation and teletreatment protocol to manage patients with BPPV during the COVID-19 pandemic. Methods Specialists in the vestibular field met through remote access technologies to discuss the best strategy to manage BPPV patients by teleconsultation and teletreatment system. Additionally, several scientific sources were consulted. Technical issues, patient safety, and clinical assessment were independently analyzed. All relevant information was considered in order to design a clinical protocol to manage BPPV patients in the pandemic context. Results Teleconsultation for BPPV patients requires a double way (video and audio) digital system. An adapted informed consent to follow good clinical practice statements must be considered. The time, trigger and target eye bedside examination (TiTRaTe) protocol has proven to be a valuable first approach. The bow and lean test is the most rational screening maneuver for patients with suspected positional vertigo, followed by most specific maneuvers to diagnostic the sub-variants of BPPV. Conclusion Although with limited evidence, teleconsultation and teletreatment are both reasonable and feasible strategies for the management of patients with BPPV in adverse situations for face-to-face consultation.

The application of social networks in the health domain has become increasingly prevalent. They are web-based technologies which bring together a group of people and health-care providers having in common health-related interests, who share text, image, video and audio contents and interact with each other. This explains the increasing amount of attention paid to this topic by researchers who have investigated a variety of issues dealing with the specific applications in the health-care industry. The aim of this study is to systematize this fragmented body of literature, and provide a comprehensive and multi-level overview of the studies that has been carried out to date on social network uses in healthcare, taking into account the great level of diversity that characterizes this industry. To this end, we conduct a scoping review enabling to identify the major research streams, whose aggregate knowledge are discussed according to three levels of analysis that reflect the viewpoints of the major actors using social networks for health-care purposes, i.e., governments, health-care providers (including health-care organizations and professionals) and social networks’ users (including ill patients and general public). We conclude by proposing directions for future research.

Higher Order Questioning

Prior research has shown that both teacher-led and recitation questions dominate in classrooms; teachers ask closed-ended questions more than open-ended questions. Even though classroom questioning has been studied in many previous studies there has been very limited research addressing the questioning of student teachers during inquiry-based biology lessons focusing on the inquiry stages: introduction, examination, and conclusion. In this study, a total of 21 lessons by 12 student teachers in primary and secondary schools were video- and audio-recorded. The recorded discussions were transcribed and the qualities of the questions were analyzed using content analysis, and the questions of student teachers were categorized into 10 different question categories. The findings revealed that primary school student teachers asked mainly for factual knowledge, concepts, and basic knowledge of species in all inquiry stages. Secondary school student teachers also asked mainly for concepts and basic knowledge of species. They also asked students to generate ideas and explain their answers, especially in the examination and conclusion stages. The present study indicates that student teachers’ questioning needs to be developed more towards higher-order questioning such as analyzing, synthetizing, and evaluating to scaffold students in inquiries and develop future teachers’ questioning skills in teacher education.
