<span lang="EN-US">The rapidly increasing number of internet of things (IoT) and non-IoT devices has imposed new security challenges to network administrators. Accurate device identification in the increasingly complex network structures is necessary. In this paper, a device fingerprinting (DFP) method has been proposed for device identification, based on digital footprints, which devices use for communication over a network. A subset of nine features have been selected from the network and transport layers of a single transmission control protocol/internet protocol packet based on attribute evaluators in Weka, to generate device-specific signatures. The method has been evaluated on two online datasets, and an experimental dataset, using different supervised machine learning (ML) algorithms. Results have shown that the method is able to distinguish device type with up to 100% precision using the random forest (RF) classifier, and classify individual devices with up to 95.7% precision. These results demonstrate the applicability of the proposed DFP method for device identification, in order to provide a more secure and robust network.</span>

The security risks and vulnerabilities associated with these resource-constrained Internet of Things (IoT) devices grow as their usability rises. Distributed Denial of Service is one of the main dangers to Internet of Things devices (DDoS). Continuous monitoring, early detection, and adaptive decision-making are necessary for IoT device security to be robust and effective. With software-defined networking (SDN), these issues can be solved, giving IoT devices the chance to manage DDoS threats in an efficient manner. This study suggests a unique SDN-based secure IoT framework that uses IP Payload Analysis and session IP counters to identify IoT device vulnerabilities and malicious traffic sent by IoT devices. The proposed methods can readily identify the DDoS attack in the SD-IoT network by analyzing several metrics, even with high traffic volumes, thanks to the DDoS attack detection module of the framework. By creating a lot of traffic from a compromised node, which is later identified and alerted, these tactics are tested on an SDN controller. The results and comparison analysis show that the suggested framework effectively and accurately detects DDoS attacks in their early stages, with a detection rate ranging from 98% to 100% and a low false-positive rate.

Purpose To determine the binocular vision status in normally-sighted school aged children who used digital devices. Methods A cross-sectional study was conducted at B.P. Koirala Lions Center for Ophthalmic Studies, Kathmandu, Nepal for a duration of one year. One hundred and eighty school aged children (71 female and 109 male) aged 7 to 17 years were included in the study. All the children underwent detailed ophthalmic and binocular vision examinations. The duration of the use of digital devices by the children were asked to either the parents or guardians present at the time of the study. The study participants were divided into two groups: children who used digital devices for the last six months (users group) and those who hadn’t used digital devices for the last six months (non users group). The users group was again divided into two subgroups: children who used digital devices for less than 3 hours per day and a day per week (low digital device users subgroup) and children who used digital devices for more than 3 hours per day and all days in a week (high digital device users subgroup). Results Accommodative amplitudes, accommodative facility, and positive fusional vergence for both near and distance were significantly reduced in the high digital device users group than in the low digital device users subgroup (p <0.01). Stereo acuity, near point of convergence, and negative fusional vergences for both near and distance were not statistically significantly different between the two subgroups. Prevalence of accommodative and vergence anomalies (except convergence insufficiency) was more in the high digital device users subgroup than in the low digital device users subgroup (p<0.01). Conclusions Children who used digital devices for a significantly greater amount of time had significantly reduced amplitudes of accommodation, accommodative facility, and positive fusional vergence both at near and distance.

Full textAbstract:
Abstract With more and more users using different devices, such as personal computers, iPads, and smartphones, they can access OPAC (online public access catalog) services and other digital library services in different contexts. This leads to the phenomenon that user’s behavior can be transferred to different devices, which leads to the richness and diversity of user’s behavior data in digital libraries. A large number of user data challenge digital libraries to analyze user’s behavior, such as search preferences and borrowing habits. In this study, we study the user’s cross-device transition behavior when using OPAC. Based on the large-scale OPAC transaction log, the online activities between device transitions in the process of using OPAC are studied. In order to predict the follow-up activities that users may take, and the next device that users may use, we detect features from several perspectives and analyze the feature importance. We find that the activity and time interval on the first device are more important for predicting the user’s next activity and the next device. In addition, features of operating system help to better predict the next device. The next device used is more likely to predict the next activity after the device transition. This study examines the cross-device transition prediction in library OPAC, which can help libraries provide smart services for users when accessing OPAC on different devices.

Full textAbstract:
Introduction: Digital device helps children enhance academic, cognitive and psychomotor skills. However, prolonged use causes physical inactivity, poor interpersonal skills and communication problems. Information on digital device use among young children in Malaysia is currently limited. Hence, this study aimed to determine the prevalence of digital device utilisation among preschool children in Kota Setar District, Kedah. Methods: A cross-sectional study at government preschools in Kota Setar District was conducted from February to April 2020. Selection of preschools and students was done using multistage simple randomisation. A self-administered questionnaire containing demographic and digital device use details was filled by parents. Results: The prevalence of digital device use among preschool children was 95.9% and mostly used smartphones (94.2%). Most children (95%) did not own the device, and usage was under supervision (95.7%). The reason for supervision was to prevent exposure to inappropriate content (70.5%). The common reasons for allowing digital device use were for educational (37.4%) and entertainment purposes (36%) through videos (30.9%) and games (30.2%). Approximately 21.5% and 50.3% of the children spent more than 1 and 2 hours on digital devices during weekdays and weekends, respectively. Conclusion: The prevalence of digital device use among the preschool children in Kota Setar District was very high. Most of them used digital devices for educational and entertainment purposes under parental supervision. However, some exceeded the recommended screen time on weekends. These findings could promote awareness of digital device use among young children and help design public health awareness programmes and future policies.

Full textAbstract:
This study investigated cognitive function in relation to the use of a computer and a touchscreen device among older adults attending a memory clinic. The entire sample ( n = 323) was categorized into four profiles, according to the frequency of digital device use (either daily or non-daily usage). Results showed that on a daily basis, 26% of the sample used both a computer and a touchscreen device, 26.9% used only a computer, 7.1% used only a touchscreen device, and 39.9% used neither type of digital device. There were significant group differences on age, education, and clinical diagnosis ( p < .001). Non-daily users of digital devices had significantly lower performance, compared with daily users of both types of digital device, on measures of global cognitive function, processing speed, short-term memory, and several components of executive function ( p < .001). Falling behind with regard to the use of digital devices might reflect underlying poor cognitive capacities.

Full textAbstract:
This study proposed a fabrication method for thin, film-based, transparent, and flexible digital microfluidic devices. A series of characterizations were also conducted with the fabricated digital microfluidic devices. For the device fabrication, the electrodes were patterned by laser ablation of 220 nm-thick indium tin oxide (ITO) layer on a 175 μm-thick polyethylene terephthalate (PET) substrate. The electrodes were insulated with a layer of 12 μm-thick polyethylene (PE) film as the dielectric layer, and finally, a surface treatment was conducted on PE film in order to enhance the hydrophobicity. The whole digital microfluidic device has a total thickness of less than 200 μm and is nearly transparent in the visible range. The droplet manipulation with the proposed digital microfluidic device was also achieved. In addition, a series of characterization studies were conducted as follows: the contact angles under different driving voltages, the leakage current density across the patterned electrodes, and the minimum driving voltage with different control algorithms and droplet volume were measured and discussed. The UV–VIS spectrum of the proposed digital microfluidic devices was also provided in order to verify the transparency of the fabricated device. Compared with conventional methods for the fabrication of digital microfluidic devices, which usually have opaque metal/carbon electrodes, the proposed transparent and flexible digital microfluidics could have significant advantages for the observation of the droplets on the digital microfluidic device, especially for colorimetric analysis using the digital microfluidic approach.

This research aims to examine parents' views on their primary school-aged children's use of digital devices. The study was designed in a descriptive phenomenology pattern. Thus, the data in the research were collected through semi-structured interviews, which is one of the qualitative research methods. As a result of the analysis, three main categories were created: “Parental Views on Digital Device Use, Parental Mediation in Digital Device Use, and Parental Awareness of Digital Device Use”. The results drew attention to the fact that parents control the time their children spend with digital devices, as well as the need for time limitation and supervision in the digital media. Additionally, the results revealed that the parents allow their children to visit websites that they believe are safe to spend time on digital devices for learning purposes. The findings of this study are anticipated to alert parents of primary school-aged children to the importance of giving their children quality time on digital media while keeping them safe.

Background: Digital media can be integrated in tele-monitoring solutions, serving as the main interface between the patient and the caregiver. Consequently, the selection of the most appropriate digital medium for the specified target group is critical to ensure compliance with the tele-monitoring system.Objectives: This pilot study aims to gather insights from patients with chronic obstructive pulmonary disease (COPD) on the ease-of-use, efficacy, effectiveness, and satisfaction of different types of digital media.Methods: Five off-the-shelf digital media devices were tested on nine patients at CIRO+ in Horn, The Netherlands. Usability was evaluated by asking patients to use each device to answer questions related to their symptoms and health status. Subsequently, patients completed a paper-based device usability questionnaire, which assessed prior experience with digital media, device dimensions, device controllability, response speed, screen readability, ease-of-use, and overall satisfaction. After testing all the devices, patients ranked the devices according to their preference.Results: We identified the netbook as the preferred type of device due to its good controllability, fast response time, and large screen size. The smartphone was the least favorite device as patients found the size of the screen to be too small, which made it difficult to interact with.Conclusion: The pilot study has provided important insights to guide the selection of the most appropriate type of digital medium for implementation in tele-monitoring solutions for patients with COPD. As the digital medium is an important interface to the patient in tele-monitoring solutions, it is essential that patients feel motivated to interact with the digital medium on a regular basis.

Full textAbstract:
New smartphones made by small companies enter the technology market everyday. These new devices introduce new challenges for mobile forensic investigators as these devices end up becoming pertinent evidence during an investigation. One such device is the PinePhone from Pine Microsystems (Pine64). These new devices are sometimes also shipped with OSes that are developed by open source communities and are otherwise never seen by investigators. Ubuntu Touch is one of these OSes and is currently being developed for deployment on the PinePhone. There is little research behind both the device and OS on what methodology an investigator should follow to reliably and accurately extract data. This results in potentially flawed methodologies being used before any testing can occur and contributes to the backlog of devices that need to be processed. Therefore, in this paper, the first forensic analysis of the PinePhone device with Ubuntu Touch OS is performed using Autopsy, an open source tool, to establish a framework that can be used to examine and analyze devices running the Ubuntu Touch OS. The findings include analysis of artifacts that could impact user privacy and data security, organization structure of file storage, app storage, OS, etc. Moreover, locations within the device that stores call logs, SMS messages, images, and videos are reported. Interesting findings include forensic artifacts, which could be useful to investigators in understanding user activity and attribution. This research will provide a roadmap to the digital forensic investigators to efficiently and effectively conduct their investigations where they have Ubuntu Touch OS and/or PinePhone as the evidence source.

Full textAbstract:
Smartphones are frequently the subject of digital screen media-based research due to their popularity. Other screen devices, such as computers, conventional TV, laptops, smart TV, and tablets, which have a significant impact on children’s and adolescents’ psychological behaviors, are rarely covered. Parents are considered the active agents who can regulate adolescents screen-based media use and control online risks. Parents of adolescents in developing countries are digital immigrants, and their consumption patterns of screen devices must be studied before exploring their media usage regulatory strategies for children and adolescents. To gather information on screen device usage patterns, including availability, usage, ownership, and screen time, a quantitative technique approach was used in the study. A statistical analysis was performed on survey data collected from 447 parent-adolescent dyadic samples (n=894). Results show a positive association between socio-economic status and the number of screen devices present in households. Parents and adolescents spend the same amount of screen time on conventional TV and smart TV as they do on smartphones. Tablets were the least used, but they had more screen time than laptops and computers. Screen time is associated with the intended use of the device. Screen time spent per device by digital immigrant parents is quite like that of their digital-native adolescents. Girls use smartphones often; boys spend more screen time with them. Parents’ screen-based media usage practices should also be regulated, as they highly influence their children’s screen time.

Network devices as media file sharing and can be used as file servers have begun to appear, just as smart router devices can be used as file servers by adding USB Thumb drive as storage media. With the diversity of router devices, it becomes a challenge in digital forensic science when a case occurs by utilizing a smart router device related to file-sharing services. Then it is necessary to study the right method in investigating smart router devices. This paper discusses the use of the live forensics acquisition method in investigating smart router devices, against system log files related to file-sharing activities. In identifying the process of searching, recognizing, and documenting potential things as digital evidence of processing devices and digital media storage. The acquisition process uses two methods, namely the live acquisition method on the router device and physical acquisition on the device that is used as storage media on the smart router.

Discussed here is a technique for testing digital devices based on the calculation and control of two or more characteristics of a binary electric signal at a reference point. Signals coming from a healthy and failed digital device that are indistinguishable by the value of one of the characteristics may differ in value of the other characteristic. The combination of test methods can significantly reduce the potential of not detecting the failure of digital device. The technique is aimed at increasing the information content of the healthy state monitoring results and the possibility of localizing failures in digital instruments and devices of power systems.

Full textAbstract:
Internet of Things (IoT) is the network of physical objects for communication and data sharing. However, these devices can become shadow IoT devices when they connect to an existing network without the knowledge of the organization’s Information Technology team. More often than not, when shadow devices connect to a network, their inherent vulnerabilities are easily exploited by an adversary and all traces are removed after the attack or criminal activity. Hence, shadow connections pose a challenge for both security and forensic investigations. In this respect, a forensic readiness model for shadow device-inclusive networks is sorely needed for the purposes of forensic evidence gathering and preparedness, should a security or privacy breach occur. However, the hidden nature of shadow IoT devices does not facilitate the effective adoption of the most conventional digital and IoT forensic methods for capturing and preserving potential forensic evidence that might emanate from shadow devices in a network. Therefore, this paper aims to develop a conceptual model for smart digital forensic readiness of organizations with shadow IoT devices. This model will serve as a prototype for IoT device identification, IoT device monitoring, as well as digital potential evidence capturing and preservation for forensic readiness.

Full textAbstract:
In the present digital age, the number of digital devices and media has multiplied, giving young children and their parents access to them anytime and anywhere. The family and home environment constitutes an important ecological context for fostering and supporting the development of safe online behaviour, as well as preventing risky online behaviour in young children. During childhood, parents play an influential role in shaping a child’s use of digital technology (DT) devices through parental practices that are shaped by their beliefs about DT. The first aim of this study was to describe preferred digital devices, activities, and emotional states related to digital device use among children aged 4 to 8 years. The second aim was to describe parental viewpoints about their children’s device use. The data was collected through online interviews with 31 children (16 girls), aged 4 to 8 years, and one parent of each of the children included in the project “Digital technology in the family: patterns of behaviour and effects on child development”. The results show that smartphones are the children’s favourite device and playing video games is their preferred digital activity. Most children reported feeling happy when they used DT devices, as well as feeling sad and angry when they had to stop using them. Parental motivation for providing children access to DT devices can be child- and parent-oriented. Parents frequently emphasised the educational aspects of their children’s device use, but they were aware of the negative and positive effects on the children’s functioning. The findings indicate that children’s daily context of living in association with DT usage is characterised by small, portable devices that are used mainly for entertainment. Additionally, their parents allow the use of such devices because they believe that DT can have a positive impact on child development, and they need to occupy children’s attention in specific situations. However, DT device usage is limited due to the awareness of the negative impact on child development.

Full textAbstract:
Using various digital devices, and being faced with digital interruptions is a given for students not only in traditional university classes but also in blended learning courses. Hence, this study (N = 201) at an Austrian university of applied sciences investigated students’ perceptions of digital device use and the digital interruptions that they face during webinars and on-campus sessions. Results show that students primarily use the same types of digital devices during webinars and on-campus sessions, i.e., computers for course-related (CR) activities, and smartphones for non-course-related (NCR) activities. Results further indicate that while the majority of students are aware of the interruptive impact that NCR activities have on their learning, the effect on others seems to be a blind spot. The reasons for NCR activities are manifold. Moreover, results suggest that students have difficulties in assessing the actual time spent on NCR activities during webinars.

The difficulties and tasks of using software when applying hybrid learning technologies in the design of digital devices are considered. The composition of the device under study has been determined. Indicators of training quality are associated with the choice of software using the example of the degree of satisfaction with the design result. Software modules for the development of digital devices have been identified. The software of the device being developed is considered as a component of a laboratory workshop. A feature of hybrid learning is noted that is associated with the complexity of prototyping and the need to ensure compatibility of project files created online with computer software modules in the university laboratory. It is proposed to create a database of educational projects to ensure continuity in the design and formation of start-up projects. An example of the design results of a digital device for indicating and monitoring a process parameter is given. The difficulties when using domestically produced integrated circuits in educational design are highlighted. It is recommended to conduct hybrid training in the design of digital devices in small groups.

Phase-shifting digital holography can be used for displacement measurement instead of strain gauge. Our research group is developing the measurement equipment for phase-shifting digital holography. Generally, in the measurement equipment, piezo stages are used as phaseshifting devices. But the piezo stage is expensive. Cheaper and smaller phase-shifting device is required in order to put the measurement equipment into practical use. In this paper, we, therefore, propose a phase-shifting device using the deflection of a cantilever and we verify whether this phase-shifting device can be usedfor digital holography.

Acoustic stethoscopes are used to monitor signals from patients. Incidentally, the connecting tube between the chest-piece and the ear-piece of common stethoscopes is known to serve as a medium for transmitting pathogens from patients to physicians or from one patient to another patient. This work presents a wireless stethoscope design with mobile integration that transmits heart sounds to mobile devices for evaluation and analysis, thus, eliminates the connecting tube. This is an extension of the previous work that presented the proof of concept of a wireless stethoscope with Bluetooth transmission. In this work, however, the chest-piece of the traditional stethoscope is integrated with microcontroller unit and Bluetooth communication device. Captured signals are processed and transmitted wirelessly to a mobile device with interface application software for recording, listening and visual display of waveforms. Following numerical simulation, a prototype was developed. Testing conducted on the prototype device using a class 2 Bluetooth device with 4[Formula: see text]dBm transmission power showed good quality received signals when the mobile device was placed 20[Formula: see text]m within indoor environments and 42[Formula: see text]m in open-space outdoor environment, beyond which degradation in quality occurs. It is worth pointing out that a smart Bluetooth device with high transmission range and data speed may produce much longer operating distance. Hence, for applications that require operating ranges beyond 50[Formula: see text]m, smart Bluetooth devices may be well suited for such systems. This system may serve as the means for monitoring patients from remote locations particularly quarantine units and can also be useful for training health personnel through broadcasting of recorded signals for analysis and evaluation by members of a medical team.

Full textAbstract:
With the global expansion of urban infrastructure and development of 5G communication technology, advanced information and communications technology has been applied to power systems and the use of smart grids has increased. Smart grid systems collect energy data using Internet-of-Things (IoT) devices, such as data concentrator units (DCUs) and smart meters, to effectively manage energy. Services and functions for energy management are being incorporated into home IoT devices. In this paper, the IoT for energy management in smart cities and smart homes is referred to as the E-IoT. Systems that use the E-IoT can efficiently manage data, but they present many potential security threats, because the E-IoT devices in such homes and enterprises are networked for energy management. Therefore, in this study, to identify vulnerabilities in the E-IoT device systems, digital forensics is applied to the E-IoT device systems. E-IoT devices supplied to Korean power systems were used to build a digital forensic test bed similar to actual E-IoT environments. For digital forensics application, E-IoT data acquisition and analysis methodology was proposed. The proposed methodology consisted of three methods—network packet data analysis, hardware interface analysis, and mobile device paired with E-IoT—which were applied to a DCU, smart meter, smart plug, smart heat controller, smart microwave, and smart monitoring system. On analyzing the user and system data acquired, artifacts such as the device name and energy consumption were derived. User accounts and passwords and energy-usage logs were obtained, indicating the possibility of leakage of personal information and the vulnerabilities of E-IoT devices.

The purpose of this study is to analyze the effect of the elderly's digital literacy on the formation of social capital and to verify the mediating effect of the elderly's digital device use self-efficacy in this relationship. To this end, the digital information gap fact-finding data conducted in 2022 was used as an SPSS 25.0 statistical program to determine the relationship between demographic characteristics, digital literacy, and self-efficacy using digital devices as independent variables and the social capital of the elderly as a dependent variable. analyzed. As a result, it was found that social capital also increased when the independent variable, digital literacy, was improved. In addition, it was analyzed that social capital increased as the self-efficacy of using digital devices in the elderly increased. Subsequently, as a result of analyzing the mediating effect of digital device use self-efficacy in the relationship between digital literacy and social capital of the elderly, digital literacy had a positive effect on social capital, and the path mediated by digital device self-efficacy was also statistically significant. Significant results were obtained. Based on the results of this study, practical efforts such as conversion of educational contents that can be used in daily life from simple contents-oriented education of educational institutions to improve the digital literacy of the elderly are suggested.

Full textAbstract:
The recent business environment can be said to be a digital era in which advanced information technology combines with existing industries to form a new industrial structure. In a multilateral society where various smart devices are distributed and a digital environment is created, the ability to respond flexibly is considered important. Therefore, it can be said that “digital competency” is presented as a competency that small business owners must have. This study investigated how digital device capabilities and digital content capabilities affect online market response for small business owners in Daegu, and analyzed the moderating effect of digital content utilization capabilities in this relationship. Further analysis was conducted based on the demographic standards of small business owners to determine how digital device capabilities and digital content capabilities appear and how digital content capabilities differ.The results of the empirical analysis are as follows. In a study of the entire group, high digital content capabilities were found to further strengthen the impact of digital device capabilities on responding to the online market. In addition, additional analysis was conducted by dividing small business owners into two groups based on the demographic criteria. In the case of women, digital content competency was found to positively control the relationship between digital device competency and online market response in small and high-educated groups.

AimsA Quality Improvement Project (QIP) was completed at South London and Maudsley NHS Foundation Trust (SLaM) to provide access of Trust laptops and smartphones (digital devices) to training doctors.The aim of the study was to assess the views of trainees before and after the rollout of digital devices. Also, to assess barriers of device uptake/usage.MethodTrainee doctors were surveyed before mass release of digital devices. Trainees were surveyed again 2 months later, providing ample opportunity to request a device.Correlated survey questions asked about training grade, expectation to request a digital device (and subsequent completed request), expected usage cases (and actual usage cases), expected benefits (and actual benefits), perceived importance of access to each device (before and after access) and barriers for device uptake. Also inquired were general comments about the project and actual lead time on device access.Result110, mixed training grade, doctors participated in both surveys combined. There was a high demand for digital devices. Laptop requests were highest, with greater clarity of potential usage cases noted for a laptop. Laptops were perceived to be the more important device to a trainee.Common usage cases for laptops were clinical work (in and out of working hours). There was also high usage around educational and audit/QIP activities. Smartphones were used only for clinical work (in and out of working hours).Having access to each device was most beneficial in saving clinician time. Other sizable benefits included improvements in communication with patients and other professionals, as well as benefits toward patient safety. The laptop specifically also improved educational access.A larger proportion of trainees requested a mobile phone than were previously expecting to. New ways of working due to the pandemic were noted to be motivating factors toward usage of devices.The biggest barrier to device uptake was the delay from request to acquisition (often over 4 weeks).Numerous respondents used personal devices for Trust related activities. This was more prevalent with smartphones, than with laptops.ConclusionDigital device rollout was a valued endeavour, with enhanced demand secondary to the pandemic. Primary usage and benefits supported clinical effectiveness. The primary access barrier was the delay from point of request to point of delivery. As SLaM, and the NHS as a whole, becomes increasingly digitised, this program is vital to allow the Trust to ensure the trainee workforce are digitally equipped to continue to deliver safe, effective and quality care.

The Android platform accounts for 85% of the global smartphone operating-system market share, and recently, it has also been installed on Internet-of-Things (IoT) devices such as wearable devices and vehicles. These Android-based devices store various personal information such as user IDs, addresses, and payment information and device usage data when providing convenient functions to users. Insufficient security for the management and deletion of data stored in the device can lead to various cyber security threats such as personal information leakage and identity theft. Therefore, research on the protection of personal information stored in the device is very important. However, there is a limitation that the current research for protection of personal information on the existing Android platform was only conducted on Android platform 6 or lower. In this paper, we analyze the deleted data remaining on the device and the possibility of recovery to improve user privacy for smartphones using Android platforms 9 and 10. The deleted data analysis is performed based on three data deletion scenarios: data deletion using the app’s own function, data deletion using the system app’s data and cache deletion function, and uninstallation of installed apps. It demonstrates the potential user privacy problems that can occur when using Android platforms 9 and 10 due to the leakage of recovered data. It also highlights the need for improving the security of personal user information by erasing the traces of deleted data that remain in the journal area and directory entry area of the filesystem used in Android platforms 9 and 10.

Background and Objectives: Due to the development of methods for analyzing signals of autonomous blood circulation control, cardiovascular system disorders can be diagnosed today in the early stages. It is promising to use specialized devices for personalized diagnosis of the cardiovascular system and monitoring its state. Research on autonomous blood circulation control systems is a complex problem both from the point of view of physiology and radiophysics. Its solution requires the development of methods and specialized devices for the analysis and registration of signals from the cardiovascular system. Therefore the object of research is the development of a photoplethysmogram sensor with a digital communication channel with a band of 0.05-30 Hz, recording the signals from the autonomous blood circulation monitoring system. Materials and Methods: To compare the level of noise and nonlinear distortions in the center of the frequency range of interest to us (at a frequency of 0.1 Hz), the power spectra of the signals were analyzed, and the coherence function was also calculated. Results: a prototype of a device for recording and analyzing a photoplethysmogram signal was developed and implemented, which makes it possible to register the signals from the circuits of autonomous blood circulation regulation. A comparative analysis of the developed device with a serial analog sensor was carried out, which demonstrated the advantages of the developed device. Conclusion: The developed broadband digital sensor can be used in wearable devices to diagnose the functional state of the cardiovascular system based on the analysis of synchronization between the circuits of autonomous regulation of blood circulation.

Screen time once referred to television. Nowadays, it includes various screen sizes that are internet-enabled devices, and the pervasive smartphone. Regardless of what kind of screen is used, screen time comprises much of life itself. Being online and offline is now fairly blurred because of the ubiquitousness of technologies, Wi-Fi and screens. This paper puts forth the notion of ‘temporal digital control’ to explain the choice of when and why smartphones and other portable digital devices are used in today’s cultural milieu, and it theorizes the ‘why’ of contemporary smartphone use is so prominent suggesting it enables temporal digital control in an autonomous space. Coupled with the engrossment of such use, the article elaborates how gazing at a digital device comprises a temporal connection, alongside a disconnection from real life, and a possible inauthenticity that could affect well-being. Recently published literature on ‘waiting’ is included to help theorize why actors choose to use digital technologies while waiting. Being preoccupied, or busy, or doing something with one’s smartphone while waiting creates a sense of alleged status, importance or connection in the form of digital temporal control. An array of vignettes is provided to demonstrate agentic disengagement with the present in a preference for moving into a temporal autonomous space of ‘perceived’ digital control. When gazing at and using a digital device, users are arguably disengaging with the temporal present, disconnecting with others who may be beside them, in preference to the creation of temporal (and digital) autonomous spaces. Regardless of what the user is doing on their smartphone or device, the use of technologies can provide a temporal autonomous space of digital control.

Modern trends in the development of digital communication lines of fixed information transmission services, as well as the characteristics of continuous channels today determine the noise immunity of radio receiving systems. The main directions of its increase in terms of the radio receiving device as a whole and the demodulator device in particular are as follows: reducing the frequency and nonlinear distortions of the signal in the linear path, increasing the stability and purity of the spectral line of oscillations of local oscillators, increasing the selectivity for the mirror and combination channels of reception, compensation for intersymbol and cross – polarization interference, improving the functioning of the automatic gain control device (reducing static and dynamic errors), improving the quality of the functioning of the carrier wave recovery device and the clock synchronization device. Taking into account all of the above factors in order to increase the overall noise immunity of a digital communication line is a very difficult and urgent task, the solution of which must begin with the development of a mathematical model of a continuous digital communication line channel. This article discusses the radio receiving path of a digital communication line in an urban environment. The obtained analytical expressions are aimed at interpreting the processes of converting digital signals in the structural elements of radio receiving systems. The originality of the mathematical model developed in the article lies in the fact that it additionally, in comparison with similar models, takes into account the following number of factors: frequency instability and phase fluctuations of oscillations of the local oscillator synthesizer, dynamic and static errors in the operation of automatic gain control devices, carrier vibration recovery devices and devices clock synchronization of radio receiving systems of digital signals.

Virtual Reality (VR) generates realistic visualization and sensation applied to various practises. Virtual Museum (VM) is a use case where VR may be applied to convince museum visitors to participate with a story told through digital content. Recently, immersive VR technologies are intensively developed providing a lot of devices which support interactive VM application. In a development of interactive VM, interaction is always depending on the selected device. Then content is tuned to fit specific device capacity; major development must be addressed again whenever the virtual environment is adapted to a new device. This paper proposed a storytelling platform to assist interactive content design which is device independent. Our framework provides high-level abstraction of story and interaction which is then translated to any low-level device. Storytelling model and interaction model are introduced to create a common language for story making. It works with a viewer, an asset manager, an event editor and a timeline to achieve virtual environments organization and interaction assignment. An example of interactive content design on our platform is presented to demonstrate the development process which can be applied to collaborative interactive content designing in the future work.

Full textAbstract:
The increasing digitalization and advancement in information communication technologies has greatly changed how humans interact with digital information. Nowadays, it is not sufficient to only display relevant data in production activities, as the enormous amount of data generated from smart devices can overwhelm operators without being fully utilized. Operators often require extensive knowledge of the machines in use to make informed decisions during processes such as maintenance and production. To enable novice operators to access such knowledge, it is important to reinvent the way of interacting with digitally enhanced smart devices. In this research, a mobile augmented reality remote monitoring system is proposed to help operators with low knowledge and experience level comprehend digital twin data of a device and interact with the device. It analyses both historic logs as well as real-time data through a cloud server and enriches 2D data with 3D models and animations in the 3D physical space. A cloud-based machine learning algorithm is applied to transform learned knowledge into live presentations on a mobile device for users to interact with. A scaled-down case study is conducted using a tower crane model to demonstrate the potential benefits as well as implications when the system is deployed in industrial environments. This user study verifies that the proposed solution yields consistent measurable improvements for novice users in human-device interaction that is statistically significant.

Wearables produce a body of data controlled by the user of the wearable, and the institution creating the device or collecting the device information, and community members engaging with the devices. This article examines the privacy policies of the top five wearable vendors of 2016 to analyze how corporations describe the bodies of digital data they amass through surveillant assemblage. Results indicate four points of agency which surround bodies of digital information: data as alter ego, data under personal control, institutional power, and community. Although scholarship often emphasizes that entities of power control information, and wearable companies emphasize the user's ability to control their information, there are multiple ways the authors can think about the data, and not addressing the complexity of data can lead to limited ideas about agency, identity, surveillance, and visibility.
