Background. Today smart watches, fitness bracelets, smart rings are must-have accessory for everyone who cares about their health. It is projected that the average annual growth of the wearable device market in 2021–2026 will be 18 %, which is respectively reflected in this segment of the Ukrainian market. Well-known electronics stores use different approaches to group the range of wearable devices, as there are no single standards to classify these products. The aim of this article is to develop a classification of wearable devices and to identify the classification featuresfor smart watches and fitness bracelets based on the analysis of the assortment presented in online stores. Materials and methods. Methods of logical analysis, generalization of scientific literature, statistical data of export and import of wearable devices were applied. Data on their assortment and grouping in well-known retail chains were used to create a classification. Results. Based on the analysis of the world market of electronic goods and the assortment of well-known retail chains, the authors propose a classification of goods related to wearable devices. In particular, there is a division of wearable devices into 7 groups (wrist devices, head devices, smart clothes, smart shoes, smart jewelry, wearable devices, medical devices), these groups include subgroups, categories and subcategories. Only a few types of wearable devices are sold on the Ukrainian market – smart watches, fitness bracelets, virtual reality glasses and smart rings. However, only two retail chains allocate these products separately in the product group "Wearable Products", the others form a large product group "Gadgets…", which according to the authors is not entirely correct, as the latter differ significantly in purpose and characteristics. Since the range of smart watches and fitness bracelets is quite wide and includes hundreds of types, it is proposed to use a number of classification features that clearly distinguish them by their functionality. Conclusion. With the COVID-19 pandemic, the wearable devices market seg­ment will continue to grow. Restrictions on mobility and an individual’s desire to monitor vital signs of their health during a pandemic will be the main factors that will influence the market for these devices. The classification of goods related to wearable devices has been developed. The classification features for smart watches and fitness bracelets, the range of which includes hundreds of types, are proposed. It is established that the main difference between smart watches and a fitness bracelets is a wider functionality of the first and a much longer battery life of the latter.

The objective of our work is to develop a novel self-powered multi-modal wireless health monitoring sensory system architecture consisting of: (i) wearable devices to continuously monitor the vital signs of a person, and (ii) environmental sensory devices which can monitor the environment and also act as multi-hop routers providing data paths from the wearable devices to a main processing unit. Together these devices can provide effective remote health monitoring of a person and also inform the person of important information. In this paper, we address the significant issue of energy depletion for the devices, which can lead to critical interruptions in monitoring, by proposing a flexible unique vibration-based energy harvesting scheme to support our architecture. This active energy harvesting scheme will allow for continuous remote monitoring of the person and his/her environment in various situations. Experimental results demonstrate the potential utilization of electromagnetic and piezoelectric vibration-based harvesting techniques for the proposed application.

This study proposes a methodology to develop adaptive operational strategies of customer-installed Energy Storage Systems (ESS) based on the classification of customer load profiles. In addition, this study proposes a methodology to characterize and classify customer load profiles based on newly proposed Time-of-Use (TOU) indices. The TOU indices effectively distribute daily customer load profiles on multi-dimensional domains, indicating customer energy consumption patterns under the TOU tariff. The K-means and Self-Organizing Map (SOM) sophisticated clustering methods were applied for classification. Furthermore, this study demonstrates peak shaving and arbitrage operations of ESS with current supporting polices in South Korea. Actual load profiles accumulated from customers under the TOU rate were used to validate the proposed methodologies. The simulation results show that the TOU index-based clustering effectively classifies load patterns into ‘M-shaped’ and ‘square wave-shaped’ load patterns. In addition, the feasibility analysis results suggest different ESS operational strategies for different load patterns: the ‘M-shaped’ pattern fixes a 2-cycle operation per day due to battery life, while the ‘square wave-shaped’ pattern maximizes its operational cycle (a 3-cycle operation during the winter) for the highest profits.

The article considers the main features of the composition of advertising texts in the German-speaking environment. The search-material is based on German language women's clothing advertising from popular German online stores and magazines (e.g., "Kenwood", "ALDI", "KIK", and etc.). The aim of this research is to study the functioning of compositional blocks in the texts of German advertising and the features of advertising texts within the German mass media discourse. The main compositional elements of the advertising text are characterized and the lexical-semantic analysis of each of its compositional parts is given. The following methods were used: the method of linguistic observation with the following procedures of systematization and classification of linguistic facts. Structural-semantic analysis was used to determine the features of the compositional structure of the advertising text. Despite the fact that advertising texts are small in volume, it is interesting to study their compositional structure, lexical and semantic content of each compositional component. The composition of the advertising text is optional and depends mainly on the pragmatic goals of each advertising text. It is important so speak about the semantics and pragmatics of compositional blocks. However, there is a certain structural pattern for creating advertising text, which takes into account all possible goals and intentions of the author of the advertisement. The article pays special attention to slogans and titles, as important compositional elements of the advertising text, because they perform both informative and motivational functions. The reader learns direct information about the products being sold from the main compositional block of the advertising text. The final part of advertisement has also its pragmatic purposes and types of manifestation. The study of advertising texts leads to the conclusion that the composition of advertising text is dynamic and depends not only on the purpose of creation, but also on the model chosen for its creation.

Critical Care Patients

BACKGROUND The continuous monitoring of vital signs of critical care patients is extremely important to ensure the patient’s safety. For this, clinicians use a Patient Monitor (PM) device which conveys the patient vital sign data through a screen and an auditory alarm system. These devices have been in use for decades. However, some limitations with PMs have been identified in the literature, for example the need for visual contact with the PM screen, which could cause decreased focus on the patient in certain scenarios, and the amount of noise generated by the alarm system. With the advance of technology, wearable devices have emerged as a potential solution for these problems. This review presents the findings of a number of studies which focus on the usability and human factors of prototype wearable devices to be used in critical care patient monitoring. OBJECTIVE The objective of this work was to review the use of prototype wearable devices by clinicians to monitor vital signs of critical care patients in hospital settings with a focus on the usability and human factors of the devices. METHODS A comprehensive literature search of relevant databases was carried out and this identified 15 relevant studies which were fully analysed by the authors. RESULTS Two types of wearable devices were identified: tactile and head-mounted/smart glasses displays. In most cases, these devices were intended for use by anaesthesiologists, but nurses and surgeons were also identified as potential users of wearable technology. Although the studies with tactile displays revealed a potential to improve clinical monitoring, usability problems related to comfort need to be overcome before they can be considered for use in clinical practice. The studies of head-mounted displays and smart glasses revealed that these devices can be useful from an ergonomics point of view in reducing the number of times the user has to avert their gaze from the patient to a separate screen, thereby increasing focus and reducing potential repetitive strain. CONCLUSIONS Researchers and designers of new wearable prototypes for critical care should strive not only for the enhanced performance of their users, but should also design for the satisfaction of the user, especially in terms of comfort and ease of use. It was found that wearable displays would serve as an accompaniment to the main PM display, and not as replacement.

Background Wearable devices can be used for continuous patient monitoring in the general ward, increasing patient safety. Little is known about the experiences and expectations of patients and health care professionals regarding continuous monitoring with these devices. Objective This study aimed to identify positive and negative effects as well as barriers and facilitators for the use of two wearable devices: ViSi Mobile (VM) and HealthPatch (HP). Methods In this randomized controlled trial, 90 patients admitted to the internal medicine and surgical wards of a university hospital in the Netherlands were randomly assigned to continuous vital sign monitoring using VM or HP and a control group. Users’ experiences and expectations were addressed using semistructured interviews. Nurses, physician assistants, and medical doctors were also interviewed. Interviews were analyzed using thematic content analysis. Psychological distress was assessed using the State Trait Anxiety Inventory and the Pain Catastrophizing Scale. The System Usability Scale was used to assess the usability of both devices. Results A total of 60 patients, 20 nurses, 3 physician assistants, and 6 medical doctors were interviewed. We identified 47 positive and 30 negative effects and 19 facilitators and 36 barriers for the use of VM and HP. Frequently mentioned topics included earlier identification of clinical deterioration, increased feelings of safety, and VM lines and electrodes. No differences related to psychological distress and usability were found between randomization groups or devices. Conclusions Both devices were well received by most patients and health care professionals, and the majority of them encouraged the idea of monitoring vital signs continuously in the general ward. This comprehensive overview of barriers and facilitators of using wireless devices may serve as a guide for future researchers, developers, and health care institutions that consider implementing continuous monitoring in the ward.
