hQChain_Leveraging towards Blockchain and Queueing Model for Secure Smart Connected Health

Blockchain facilitates a broad spectrum of applications such as transaction of cryptocurrency, catering to financial services, designing and constructing smart cities and so on. It has astounding benefits including accountability, consistency and decentralization. Smart healthcare can be exemplified as utilizing propitious electronic technology safeguarded with blockchain for superior diagnosis of the disorders, improvised and cost-effective treatment of the patients, and enhanced quality of lives. Since, blockchain in smart healthcare architecture hosts substantial amount of patient data queueing models play a pivotal role to efficiently process the data. In this paper, it highlights the concepts of blockchain, then delve into the smart healthcare architecture and then deal with the several queueing models that already exist. It proposes the model i.e. hQChain which is inculcating M1,b/Mb/1 queueing model into blockchain based smart healthcare architecture. It offers a queuing mathematical and analytical model to analyze and study the performance measurement of hQChain model.

Hybrid Workload Enabled and Secure Healthcare Monitoring Sensing Framework in Distributed Fog-Cloud Network

The Internet of Medical Things (IoMT) workflow applications have been rapidly growing in practice. These internet-based applications can run on the distributed healthcare sensing system, which combines mobile computing, edge computing and cloud computing. Offloading and scheduling are the required methods in the distributed network. However, a security issue exists and it is hard to run different types of tasks (e.g., security, delay-sensitive, and delay-tolerant tasks) of IoMT applications on heterogeneous computing nodes. This work proposes a new healthcare architecture for workflow applications based on heterogeneous computing nodes layers: an application layer, management layer, and resource layer. The goal is to minimize the makespan of all applications. Based on these layers, the work proposes a secure offloading-efficient task scheduling (SEOS) algorithm framework, which includes the deadline division method, task sequencing rules, homomorphic security scheme, initial scheduling, and the variable neighbourhood searching method. The performance evaluation results show that the proposed plans outperform all existing baseline approaches for healthcare applications in terms of makespan.

Design and Evaluation of Large-Scale IoT-Enabled Healthcare Architecture

Employment of the Internet of Things (IoT) technology in the healthcare field can contribute to recruiting heterogeneous medical devices and creating smart cooperation between them. This cooperation leads to an increase in the efficiency of the entire medical system, thus accelerating the diagnosis and curing of patients, in general, and rescuing critical cases in particular. In this paper, a large-scale IoT-enabled healthcare architecture is proposed. To achieve a wide range of communication between healthcare devices, not only are Internet coverage tools utilized but also satellites and high-altitude platforms (HAPs). In addition, the clustering idea is applied in the proposed architecture to facilitate its management. Moreover, healthcare data are prioritized into several levels of importance. Finally, NS3 is used to measure the performance of the proposed IoT-enabled healthcare architecture. The performance metrics are delay, energy consumption, packet loss, coverage tool usage, throughput, percentage of served users, and percentage of each exchanged data type. The simulation results demonstrate that the proposed IoT-enabled healthcare architecture outperforms the traditional healthcare architecture.

Potential Space in Hospitals: Insight From a Health Psychologist

Objective: Humanization is a challenge for the future of healthcare. Architecture may play a major role in designing spaces that enhance communication and help the patient to maintain mental health during physical illness. Health psychologists struggle to find adequate space for taking care of their patients. There is an urgent need to better define how relational space, defined here as potential, can be guaranteed in everyday hospital psychological consultations. Background: The author relates to his work as a health psychologist and psychotherapist in a consultation-liaison psychiatry (CLP) service operating in a general hospital in Lugano (Switzerland). Methods: An autoethnographic method is applied through calling on childhood memories on architecture and analyzing insights regarding the healthcare space in everyday work as a psychologist. Photographs and drawings are employed as evocative material. Results: Autoethnographical data show that building interiors can be a metaphor for an inner dimension. Spaces can be perceived as depersonalized in hospital. Through psychoanalytical theory, it is argued that space becomes ideal for CLP if it can ensure the continuity of the patient’s self during hospitalization. Proximity, confidentiality, and privacy are healthcare design requirements to be considered for favoring potential space and psychological intervention. Conclusion: Fostering potential space represents an outstanding challenge for the hospital of tomorrow in order to humanize healthcare spaces and promote a person-centered approach.

ANALYSIS OF THE FORMATION OF INTERMEDIATE RECREATIONAL SPACES OF MEDICAL INSTITUTIONS

This article the formation of intermediate recreational spaces of medical institutions was studied. The purpose of the publication is to analyze scientific and practical research on the formation of intermediate recreational spaces based on facilities in medical institutions. And also to identify the features of their formation in the design of modern medical institutions. Analysis of prototypes of intermediate recreational spaces in Europe and the world has shown that they are widely used in medical institutions and are an important recreational component. That is why it is advisable to consider them as a component of modern medical institutions and an important element of healthcare architecture. The analysis of the analogues allowed us to note that intermediate recreational spaces in modern medical institutions play a major role and performs important functions. Such functions as: recreational; ecological; economic; social; aesthetic; health; cultural; distributive. The features of the formation of these elements were identified, on the basis of which the general functions of the formation of the considered spaces were identified. Based on this, the general means of their formation were determined and the main groups of structure-forming elements were identified, including the means of landscape design. The general elements of the formation of intermediate recreational spaces in medical institutions were identified: - head ones - with an active degree of pastime and a large area of space of a medical institution: reception halls, terraces and green roofs, patios, atriums, passage and winter intermediate spaces; - minor - of an average degree of saturation of pastime and an average area of the space of a medical institution (terraces, verandas, reception rooms, galleries, special chambers, spaces and corridors for waiting) - additional - with a minimum degree of pastime and a minimum area of hospital space, such as balconies, loggias, bay windows, ramps, ramps. The identified elements can be located both in the external and in the internal space of medical institutions, thereby forming not only the environment for pastime, but the planning and architectural-compositional structure of the object itself.
