The article offers an analysis of the phenomena of distance and e-learning, presents the stages of the formation of the technology of the distance-organized educational process. The level of formation of ICT competencies of teachers, students of pedagogical universities, students of general educational organizations is analyzed. The issues of operational “online” and delayed “offline” support of teachers’ activities related to the implementation and participation in ICT projects within the framework of their own professional activities are considered. The work is based on real experience in implementing projects on the territory of the Altai Territory (2012–2018), including the experience of supporting projects and courses on the formation of ICT competencies, including models for organizing operational counseling for teachers using chat bots, specialized groups in social networks, sites with forums, etc. The issues of online support of the offline organized educational process of students are considered, which corresponds to the implementation and support of any subject course of study. This material is based on teaching experience during the quarantine period associated with the coronavirus epidemic. The article introduces the concepts of vertically and horizontally organized distributed support, discusses various ways and methods of implementing this support. The author’s technology of organizing distance courses for advanced training of teachers on the topic of ICT implementation in the educational process is described. It is indicated that when organizing support for remote and intramural-distance projects and courses, the most optimal is the use of a combination of synchronous and asynchronous communication.

Causal Consistency for Reversible Multiparty Protocols

In programming models with a reversible semantics, computational steps can be undone. This paper addresses the integration of reversible semantics into process languages for communication-centric systems equipped with behavioral types. In prior work, we introduced a monitors-as-memories approach to seamlessly integrate reversible semantics into a process model in which concurrency is governed by session types (a class of behavioral types), covering binary (two-party) protocols with synchronous communication. The applicability and expressiveness of the binary setting, however, is limited. Here we extend our approach, and use it to define reversible semantics for an expressive process model that accounts for multiparty (n-party) protocols, asynchronous communication, decoupled rollbacks, and abstraction passing. As main result, we prove that our reversible semantics for multiparty protocols is causally-consistent. A key technical ingredient in our developments is an alternative reversible semantics with atomic rollbacks, which is conceptually simple and is shown to characterize decoupled rollbacks.

Online-Semisupervised Neural Anomaly Detector to Identify MQTT-Based Attacks in Real Time

Industry 4.0 focuses on continuous interconnection services, allowing for the continuous and uninterrupted exchange of signals or information between related parties. The application of messaging protocols for transferring data to remote locations must meet specific specifications such as asynchronous communication, compact messaging, operating in conditions of unstable connection of the transmission line of data, limited network bandwidth operation, support multilevel Quality of Service (QoS), and easy integration of new devices. The Message Queue Telemetry Transport (MQTT) protocol is used in software applications that require asynchronous communication. It is a light and simplified protocol based on publish-subscribe messaging and is placed functionally over the TCP/IP protocol. It is designed to minimize the required communication bandwidth and system requirements increasing reliability and probability of successful message transmission, making it ideal for use in Machine-to-Machine (M2M) communication or networks where bandwidth is limited, delays are long, coverage is not reliable, and energy consumption should be as low as possible. Despite the fact that the advantage that MQTT offers its way of operating does not provide a serious level of security in how to achieve its interconnection, as it does not require protocol dependence on one intermediate third entity, the interface is dependent on each application. This paper presents an innovative real-time anomaly detection system to detect MQTT-based attacks in cyber-physical systems. This is an online-semisupervised learning neural system based on a small number of sampled patterns that identify crowd anomalies in the MQTT protocol related to specialized attacks to undermine cyber-physical systems.

Using Technology to Support Distributed Teams: A Work System-Based Study of an Interdisciplinary Team Responding to COVID-19

Effective teams are essential to meet the complex and dynamic requirements during pandemic response. This case study analyses the work system of mobileSHIELD, a distributed team developing a diagnostic test in response to the COVID-19 pandemic. We conducted interviews with 18 team members to understand how work system design influences the use of technology to support distributed teams. We identified six work system barriers and facilitators. The barriers related to rapidly adopting new technologies and not utilizing features of technologies that support relationships. The facilitators were related to the use of technology to support informal communication, synchronous and asynchronous communication, and mobile technology to improve productivity and collaboration. Our findings indicate technology that is mobile, cloud based, simple and user-friendly can support distributed teams, in particular by improving asynchronous communication. Future research will holistically explore implications for work system design to support interdisciplinary teams responding to societal crises.

A Novel Solution for Controlling Hardware Components of Accelerators and Beamlines

A novel approach to the remote-control system for the compact multi-crystal energy-dispersive spectrometer for x-ray emission spectroscopy (XES) applications has been developed. This new approach is based on asynchronous communication between software components and on reactive design principles. In this paper, we identify the challenges we have faced, our solution to them as well as the implementation and future development prospects. The main motivation of this work was the development of a new holistic communication protocol that can be implemented to control various hardware components.

An Analysis of Electronic Health Record Work to Manage Asynchronous Clinical Messages among Breast Cancer Care Teams

Objective Asynchronous messaging is an integral aspect of communication in clinical settings, but imposes additional work and potentially leads to inefficiency. The goal of this study was to describe the time spent using the electronic health record (EHR) to manage asynchronous communication to support breast cancer care coordination. Methods We analyzed 3 years of audit logs and secure messaging logs from the EHR for care team members involved in breast cancer care at Vanderbilt University Medical Center. To evaluate trends in EHR use, we combined log data into sequences of events that occurred within 15 minutes of any other event by the same employee about the same patient. Results Our cohort of 9,761 patients were the subject of 430,857 message threads by 7,194 employees over a 3-year period. Breast cancer care team members performed messaging actions in 37.5% of all EHR sessions, averaging 29.8 (standard deviation [SD] = 23.5) messaging sessions per day. Messaging sessions lasted an average of 1.1 (95% confidence interval: 0.99–1.24) minutes longer than nonmessaging sessions. On days when the cancer providers did not otherwise have clinical responsibilities, they still performed messaging actions in an average of 15 (SD = 11.9) sessions per day. Conclusion At our institution, clinical messaging occurred in 35% of all EHR sessions. Clinical messaging, sometimes viewed as a supporting task of clinical work, is important to delivering and coordinating care across roles. Measuring the electronic work of asynchronous communication among care team members affords the opportunity to systematically identify opportunities to improve employee workload.

Classification and analysis of asynchronous communication content between care team members involved in breast cancer treatment

Objective A growing research literature has highlighted the work of managing and triaging clinical messages as a major contributor to professional exhaustion and burnout. The goal of this study was to discover and quantify the distribution of message content sent among care team members treating patients with breast cancer. Materials and Methods We analyzed nearly two years of communication data from the electronic health record (EHR) between care team members at Vanderbilt University Medical Center. We applied natural language processing to perform sentence-level annotation into one of five information types: clinical, medical logistics, nonmedical logistics, social, and other. We combined sentence-level annotations for each respective message. We evaluated message content by team member role and clinic activity. Results Our dataset included 81 857 messages containing 613 877 sentences. Across all roles, 63.4% and 21.8% of messages contained logistical information and clinical information, respectively. Individuals in administrative or clinical staff roles sent 81% of all messages containing logistical information. There were 33.2% of messages sent by physicians containing clinical information—the most of any role. Discussion and Conclusion Our results demonstrate that EHR-based asynchronous communication is integral to coordinate care for patients with breast cancer. By understanding the content of messages sent by care team members, we can devise informatics initiatives to improve physicians’ clerical burden and reduce unnecessary interruptions.
